Many words and phrases can offend me, but I find the term “shut up” the most offensive.

For example, you are talking and someone tells you to “shut up.” They want you to stop talking and to be silent. I find such an intrusion to be very impolite, as this person is taking away your right to speak. And, the person is doing it in an unmannerly way.

While there are times when you may feel it is important to interrupt someone when they are talking, I think that using the term, “shut up,” to do so is extremely rude.
